js的農歷演算法_農歷的演算法是怎麼算的

㈠ JS獲取農歷日期的原理是什麼，有人能解釋下嗎

有國際化、皮膚和一些配置的文件，這些文件會互相調用，不能單獨工作，你頁面上的寫法是正確的，我想應該是js類庫缺少文件或者是文件的相對位置被改變了。

㈡有誰知道js的農歷演算法是怎麼寫出來的

其實我也不懂這個演算法，網上粘貼的，我覺得可以不去深究這個公式，反正有現成代碼：

設：公元年數－1977（或1901）＝4Q＋R
則：陰歷日期=14Q+10.6(R+1)+年內日期序數-29.5n
（注:式中Q、R、n均為自然數，R<4）
例：1994年5月7日的陰歷日期為：
1994－1977＝17＝4×4＋1
故：Q＝4，R＝1 則：5月7日的陰歷日期為：
14×4+10.6(1+1)+(31+28+31+30+7)-29.5n
=204.2- 29.5n
然後用29.5去除204.2得商數6......27.2，6即是n值，余數27即是陰歷二十七日。

㈣求js詳細時間代碼，年月日星期時分（秒），陰歷日期

㈤用js實現離當前時間最近的節日的涵數，如果能用給追加分數。

㈦農歷的演算法是怎麼算的

農歷一年為12或13個月，每個月天數依照月亮圍繞地球運行周期而定，為29或30天，閏年為13個月，中國農歷年平年為353或354天，閏年為384或385天，平均每年約為365.2422天（即地球環繞太陽一周的時間）。

農歷基本上以19年為一周期，由於農歷一年約為355日，與地球年相差約11日左右，所以每3年要置一閏月，每19年要置7個閏月。有閏月的年份也叫閏年，具體閏哪個月，則要視節氣情況靈活而定。如公歷的2001年5月27日、1982年5月27日和1963年5月27日這個日子，都是閏四月初五。

閏月加到哪個月，以農歷歷法規則推斷，主要依照與農歷的二十四節氣相符合來確定。自冬至開始，逢單數為節氣，逢雙數為中氣，如輪到一個月只有節氣沒有中氣，即為上一個月的閏月。農歷的閏月天數與正常月份天數一樣，為29或30天。

(7)js的農歷演算法擴展閱讀：

農歷的優點：

1.農歷是定歷，它具有天文年歷的特性，能很好地和各種天象對應，如它的節氣嚴格對應太陽高度，歷日較嚴格地對應月相，閏月的不發生頻率和發生頻率對應地球近日點和遠日點，其它天象如日出日沒，晨昏蒙影，五星方位，日月食，潮汐等，就連歷月也大致對應太陽高度；

2.農歷歷月的天數只有29日和30日兩種，且由定朔日規定，人為因素最小，不易隨意改動；

3.歲首有較強的天文學意義，具有陰月陽年的天文學意義；

4.陰陽合歷，最體現漢民族天人合一、陰陽和諧的傳統文化；

5.干支紀年和十二生肖紀年循環使用；由於它包含節氣十分利於四季劃分，由於它包含月相，所以也十分反映潮汐，日月食等天象和月亮對氣候的影響。
